If you want to experience Nostr MLS private chat, try XChat(for Nostr).

Imagine you have a family circle on your family’s private relay, and a friends circle on a relay shared with your friends. Only members of each circle can send and receive messages.
You simply switch to the family circle to chat with family, and to the friends circle to chat with friends.
One identity can join multiple circles, and each circle’s data stays completely separate.

Now with 0xchat-lite, you can switch to your relay mode when you’re online, and switch to the bitch@ mode when you’re offline.

Hi nostr — 0xchat-lite v0.1.0 beta is out!
This is 0xchat lite version, a new lightweight chat client built around MLS — and it’s a bit different from the main 0xchat app.
* Focused, minimal UI for essential conversations
* Separate, platform-native UIs for iOS and Android
* Circle concept: easily switch between multiple circles, each with its own database, relay & file server configuration
**Other privacy features:**
* Encrypted local database
* Encrypted media uploads
* Automatic group ID rotation when members or group info change
* Only connects to relays configured for each circle — no hidden connections
It’s still in beta, so feedback is very welcome!
Try it out and help build a better, privacy-first chat experience on nostr. 🫶

Is this intended to be used for friend requests? Sounds similar to a one-time invite link. Curious to hear more!

MLS stores key packages on the local device, so for state sharing, we need to migrate this part. The remaining events can be synced via relays. I also agree with you — having a private relay is a better choice, especially one relay per group. This is also a key design focus for me in 0xchat lite.

A NIP-29 relay not only forwards messages, but also maintains and synchronizes group state.

-- #0xChat looks abandoned
why? 😂

2025-05-21 02:26:05 UTC

- reply

Unlike notes, group messages rely on group management, and keeping group state in sync across multiple relays is very difficult — if not impossible.

2025-05-21 02:14:02 UTC

Currently, it's not supported. Personally, I prefer using a single relay for group chats. The main advantage is message stability and consistency.
The downside is the single point of failure — but I believe this can be addressed by implementing a backup and migration mechanism to move the chat history to a new relay if needed.

I think this is a problem with fiatjaf's implementation, not a problem with NIP-29 itself.

why? 😅

Not yet, but I can add support in 0xChat Wallet for invoice deep linking. Once Amethyst supports jumping to 0xChat, zapping via your 0xChat wallet would be possible.

It’s not a bad idea imo, but rather a trade-off. Sharing the device key increases the risk of leakage, which goes against the intention of forward secrecy.

2025-02-14 02:28:38 UTC

- reply

I’ve looked into it. Could it be that there is an error during the execution of `checkRelayAuth`? Do you have more specific error logs? The AUTH works fine on my side.

It seems that https://www.nostrchat.io/ allows creating channels, but I don't know how to share the created channel to open it in other apps.

which group relay are you using?

2024-12-20 07:20:53 UTC

Yes, but the iOS/Android versions need to be updated to the next version for that to work.

I do believe Simplex does a better job in terms of privacy. I just want to clarify: the NIP-44 encryption algorithm we use has been audited. Please check out this report:
https://github.com/paulmillr/nip44/blob/ce63c2eaf345e9f7f93b48f829e6bdeb7e7d7964/audit-2023.12.pdf
Additionally, the NIP-17 DM we use has been merged into the main Nostr branch, which can prevent metadata leaks

Progress is at 80%, but I still want to hear everyone's opinions. Do you want a 'Moment' feature similar to WhatsApp or WeChat on 0xchat? Or do you just want a simple chat function? 😄 😄
